Created a React app during my web development bootcamp that can keep track of notes the user adds and deletes. You can test it out here.
One of the best features of using React is that the application can be seamlessly scaled and fully responsive. It is a very smooth process to add and remove the notes and resizing the window will shrink the content in a neat way. This makes it extremely easy to cater to users with an assortment of devices and even port it over to a mobile application.
